Definitions

  • the present invention relates to a detachable coupling device, and more particularly to a coupling device which couples a rotatable element to a high torque transmission drive means.
  • clamping devices which couple a cylindrical member or shaft to a concentrically arranged support.
  • the known clamping devices mount symmetrical inner and outer rings on the cylindrical member.
  • the radial clamping force achieved by drawing the inner and outer rings together by means of axially spaced clamping rings has been found to be unsatisfactory, especially when it is desired to rotate the cylindrical member by connecting the clamping device to a high-torque rotatable transmission drive.
  • Another object of the present invention is to prevent slippage without requiring a plurality of additional axially spaced coupling devices.
  • a further object of the present invention is to provide interchangeable coupling devices.
  • one feature of the present invention is to provide an inner ring having a contoured outer circumferential surface positioned about a rotatable element, such as a shaft.
  • An outer ring having a larger diameter than the inner ring is radially spaced of the latter and has a contoured inner circumferential surface which defines with the contour of the outer circumferential surface of the inner ring, a pair of axially spaced V-shaped recesses which converge towards each other.
  • the outer ring has a larger cross-sectional area in axial section than the inner ring.
  • a pair of axially spaced generally V-shaped clamping rings have surface portions which will wedge against the walls of the V-shaped recesses when a plurality of clamping screws are rotated in requisite direction to effect the drawing together of the clamping rings.
  • the wedging action generates a radial force on the shaft, as will be described in greater detail below.
  • the larger axial cross-sectional area of the outer ring causes a correspondingly more affirmative clamping force on the shaft than is provided by the clamping devices of the prior art, and thereby overcomes the prior art slippage problem without requiring a plurality of additional clamping devices.
  • the larger cross-sectional area of the outer rings allows the outer peripheral region thereof to be modified so as to be coupled to a high torque transmission drive means.
  • the variously modified outer circumferential regions permit the circumferentially complete outer rings to be interchanged depending upon the loading and high-torque transmission requirements required by the drive system.
  • FIG. 1 is a partially sectioned view of an embodiment of the present invention
  • FIG. 2 is a partially sectional view of the embodiment of FIG. 1 showing a modification of the outer ring;
  • FIG. 3 is a partially sectioned view of a second embodiment of the present invention showing yet another embodiment of the outer ring.
  • FIG. 4 is a partially sectioned view of the embodiment of FIG. 3 showing yet another modification of the outer ring.
  • reference numeral 10 identifies a rotatable element, such as a shaft, having an axis and supported in a hub 9 which has an axially extending hub sleeve attachment 8.
  • An inner ring 2 which may be circumferentially complete or incomplete, has a cylindrical inner circumferential surface and is sealingly mounted on the hub sleeve attachment 8.
  • the inner ring 2 has an outer circumferential surface contoured with a pair of inclined planar wall portions.
  • the first pair of wall portions diverge radially outwardly in double-conical configuration, that is, they diverge radially outwardly towards the opposite axial ends of the inner ring 2 as shown in FIG. 1.
  • An outer ring 1 has a larger diameter than the diameter of the inner ring 2 and is concentrically and radially spaced of the latter.
  • the inner circumferential surface of the outer ring 1 is contoured with a second pair of inclined wall portions.
  • the second pair of wall portions is the mirror-image of the first pair of wall portions.
  • the two pairs of wall portions define with each other a pair of axially shaped annular V-shaped recesses, each of which converges inwardly in direction towards each other from one axial end of the respective rings 1, 2.
  • the outer circumferential region of the outer ring 1 is cylindrically shaped as shown in FIG. 1, or may be modified as will be described in detail later herein.
  • a pair of pressure clamping rings 6 are axially spaced along a line parallel to the axis of the shaft 10 and have V-shaped surface portions which are partially received respectively in each of the V-shaped recesses.
  • a plurality of clamping screws 7 are circumferentially distributed on the clamping rings 6 and are operative to draw the latter together.
  • the leading end portions of the screws 7 are threaded and mesh with a cooperating threaded bore provided in the associated clamping ring 6.
  • the trailing portions of the screws 7 pass with clearance through aligned bores in the other associated clamping ring 6.
  • the screws 7 have a head portion which abuts against the last-mentioned clamping ring and is adapted to be turned by a tool in conventional manner.
  • V-shaped surface portions will wedge against the walls of the V-shaped recesses, thus generating the radial clamping force to frictionally act initially upon the hub attachment 8 and, in turn, upon the shaft 10.
  • the outer ring is radially expanded, and the inner ring is inwardly compressed into tight engagement with the outer surface of the rotatable shaft element 10.
  • the larger axial section cross-sectional area of the outer ring 1 causes a more affirmative clamping force to be realized than was obtained by the symmetrical outer and inner rings of the prior art described above.
  • the asymmetrical rings allow the outer circumferential region of the outer ring to further comprise a drive-coupling portion. As can be seen in FIG. 1, the drive-coupling portion extends radially a greater distance than the inner ring 2 extends in the radial direction.
  • the outer circumferential region of the outer ring 1 is adapted to be used in many types of transmission drive systems.
  • the outer circumferential region is cylindrically shaped so that the coupling device can be coupled to a conventional belt drive system.
  • the outer circumferential region may be smooth or roughened to increase the frictional coupling connection.
  • the outer circumferential region of the drive coupling portion has peripheral grooves 3 so that the coupling device can be coupled to a V-belt or screw-drive transmission system which are conventional in the art.
  • the outer circumferential region of the drive coupling system has axially extending teeth 4 which couple the device to a conventional gear-tooth drive system.
  • This orientation of the teeth 4 assures that the drive system is not restricted only to drive systems having rotating elements turning about a line normal to the axis of the shaft 10, but are intended to include drive systems having rotating elements turning about a line parallel to the axis of the shaft 10.
  • the drive coupling portion has a flange-type ring attachment 5 which is adapted to couple the shaft to any rotatable transmission drive system.
  • FIGS. 3 and 4 in contrast to FIGS. 1 and 2, the inner circumferential surface of the inner ring 2 is shown to be sealingly mounted directly on the shaft 10. In this embodiment, the radial clamping force is even more affirmative in the localized area of engagement.
  • the outer rings 1 are circumferentially complete and are easily interchangeable with one another. Loosening the clamping screws 7 will reverse the wedging action and permit an outer ring to be used at another location depending upon the desired loading and required torque transmission requirements.
  • the rings 1, 2 are preferably made of spring steel, but other suitable materials can be used.
  • the clamping ring 6 may be made of spring steel or of any other rigid metallic material.
